ALEXA FLUOR 594 FREE ACID 5 mg，A33082，Applied Biosystems

Alexa Fluor® 594 Carboxylic Acid is a non-reactive form of Alexa Fluor® 594 that can be used as a reference standard for dye-conjugates. Additionally, this carboxylic acid derivative can be converted to an amine-reactive ester using standard chemical techniques or coupled to hydrazines, hydroxylamines, and amines in aqueous solution using water-soluble carbodiimides such as EDAC (Cat. No. E2247).

Characteristics of Alexa Fluor® 594 dye include:

• Laser line: 561 or 594 nm
• Common filter set: Texas Red
• Excitation maxima: 590 nm
• Emission maxima: 617 nm

More About Alexa Fluor® 594 Dye
Alexa Fluor® 594 dye is a bright, red-fluorescent dye that can be excited using the 561 or 594 nm laser lines. It serves as a direct replacement for Texas Red® dye with bright signal and excellent photostability, especially in fixed cells. Alexa Fluor® 594 dye is commonly used with DAPI, and Alexa Fluor® 488 and 647 dyes for multiplexing. Learn more about this dye and related products.

Discover the Benefits of the Alexa Fluor® Dye Series
Compared to traditional dyes, Alexa Fluor® dyes are brighter, more photostable, and more pH-resistant between pH 4 and 10. And generally when using Alexa Fluor® dyes, higher degrees of labeling can be achieved without intramolecular quenching.
